精细油藏描述研究中的几个问题探讨

Problems with the fine description of reservoirs

从精细油藏描述研究现状入手,对比分析了目前国内外精细油藏描述研究的优势和不足。总体上国内精细油藏描述研究与国外相比还有较大差距。目前精细油藏描述研究中还存在断裂体系刻画多解性、单砂体预测精度低、剩余油分布有效研究方法技术不成熟、储层在开发过程中变化规律研究薄弱等问题。结合自身研究实践,针对上述问题,提出了加强各种基础地质实验、重视储层地质成因分析、新技术方法的应用、综合性研究降低地质多解性、用动态的思维开展精细油藏描述研究和加强精细油藏描述研究信息化平台建设等技术对策。

The advantages and disadvantages of fine description of reservoirs in China and abroad were discussed and compared. Some problems in the fine description of reservoirs in China were pointed out,such as the multiexplanation of fracture systems,low accuracy of single sand body prediction,and poor prediction of residual oil distribution and reservoir development rules. Six countermeasures were proposed,including basic geologic experiments,reservoir geology origin analysis,new technique application,comprehensive analysis to reduce multiexplanation,reservoir fine description with dynamic thought,and information platform construction.
